This theory is intended to showcase and test different features of the \argo\ proof method.
The \argo\ proof method can be applied to propositional problems, problems involving equality
reasoning and problems of linear real arithmetic.
The \argo\ proof method provides two options. To specify an upper limit of the proof methods
run time in seconds, use the option \argo_timeout\. To specify the amount of output, use the
option \argo_trace\ with value \none\ for no tracing output, value \basic\ for viewing the
underlying propositions and some timings, and value \full\ for additionally inspecting the
proof replay steps.
